Abstract
A soft handover method with gateway site diversity between a first nominal gateway to a relay satellite of a space telecommunication system and a second redundant gateway to the same satellite comprises a soft handover preparation phase, and a soft handover execution phase that are executed in succession. During the execution phase, a first switchover of the traffic at the ground segment level to the second redundant gateway, and a second switchover at the level of the segment on board the satellite between a first nominal access link of the first nominal gateway and a second redundant access link of the second redundant gateway are finely synchronized.
